The Y-shaped oil-gas balance suspension system for the rear axle of the wide-body vehicle comprises damping assemblies which are arranged on the two sides of a vehicle frame and connected with an axle, the vehicle frame is connected with the axle through connecting rods, the connecting rods are at least one Y-shaped frame installed below the vehicle frame, a cross beam fixedly installed on the two sides of the vehicle frame is arranged below the middle of the vehicle frame, and the cross beam is connected with the axle. The open end of the Y-shaped frame is fixedly connected with the two ends of the axle respectively, and the closed end is hinged to the middle of the cross beam through a knuckle bearing. An original multi-connecting-rod suspension structure is simplified, the frame and the axle are connected through the Y-shaped frame, the folding end of the Y-shaped frame is hinged to the cross beam through the knuckle bearing, and due to simplification of a suspension system, the knuckle bearing hinged to the cross beam has more choices, and the problem that space is limited due to the multi-connecting-rod structure is solved.

    本发明提供了一种宽体车后桥用Y型油气平衡悬挂系统,包括设置在车架两侧与车桥连接的减震组件,所述车架与车桥通过连杆连接,所述连杆设置为至少一个安装在车架下方的Y型架,所述车架中部下方设置有与车架两侧固定安装的横梁,所述Y型架的敞口端分别与车桥的两端固定连接,合拢端通过关节轴承铰接于横梁中部。本发明通过将原有的多连杆悬挂结构简化,通过Y型架,实现车架与车桥的连接,Y型架的合拢端通过关节轴承与横梁铰接,由于悬挂系统的简化,与横梁铰接的关节轴承具有更多的选择,解决了因多连杆结构导致空间受限的问题。
